SI Fantasy Football app debuts on Facebook

In May, Sports Illustrated and Kabam (formerly known as Watercooler) announced that they were bringing one of the most popular real-life social games to Facebook -- fantasy football. Now, right before the 2010 football season kicks off, SI Fantasy Football arrives on Facebook.

Much like the other fantasy football apps/sites out there, SI Fantasy Football lets you join or create a league, set up a draft, keep track of your players' scores in real-time and rap with other armchair quarterbacks in a chat area and on message boards. The big differentiator with this app is that it lives on Facebook, which means you can invite Facebook friends to join your league with a few clicks of the mouse (you also have the option to invite friends via email). Then there's the real strength of this app -- the ability to post trash talk directly to your Facebook wall.
